mostly students, mostly obama supporters . mostly obama supporters on day one. now, republicans say that's overblown. if you've made up your mind to vote even before the debates, you are going to be for one candidate or the other no matter what and you are going to vote. so if you're voting early, voting late, it doesn't matter. but one of the places obama thinks it helps is they had a big swell in the youth vote last time. they had the support in the bells, but, wolf, frankly they down this time. sometimes college students get a bitdistracted. one of the things, the president of the university of iowa democrats, her job is to tell all of her friends, all of the fellow students vote now. >> things come up. you can have an exam. you can wait until election day and not know where your precinct is. a lot of student haves to go to elementary schools, they don't have cars, they don't know where it is, any extra obstacle can keep students homeda early voting gives us 40 more chances to catch people. >> reporter: now, republicans traditionally don't invest as much time
